That's a feature request.  Chet can discuss that with you.

All I can tell you is that this feature is not in any way suitable for
retrieving an element from an associative array.  If it actually existed,
which of course it doesn't.

I cannot make ANY sense of this.  I don't know what you're doing or why.

Whatever you're doing, it's ridiculously convoluted and obscure.  There
is probably some MUCH easier way to achieve the goal.  If you would just
tell us the goal, we might be able to help you do it.
